[Gluster-users] really large number of skipped files after a scrub

[cYuSeDfZfb cYuSeDfZfb]

Hi,

Just to follow up my first observation from this email from december:
automatic scheduled scrubs that not happen. We have now upgraded glusterfs
from 7.4 to 10.1, and now see that the automated scrubs ARE running now.
Not sure why they didn't in 7.4, but issue solved. :-)
